> My Xbox tells me my network sucks because it doesn't have ipv6
Pretty sure that it's complaining about lack of upnp. Which, yes, would not be an issue if we had ipv6... but ironically consoles typically have been slow to adopt ipv6 support themselves, so I'm curious if the xbox even supports it..
No they complain about ipv4 because they’re worried about layers of cgnat introducing latency which for gaming is bad.
Xbox live has had it for years because ipv6 means no nat and lower latency. It’s been there since at least the 360.
Steam and Meta Quest are both terrible at ipv6. At least from a year or so back. My home netowkr supported good ipv6 networking on two providers. Steam games would mess up constantly and Quest would take minutes to load.
Steam having issues makes sense given its been around ages. Meta Quest is all new OS and code yet they managed to bork ipv6. Super annoying.
